John Navins, known as Jack, volunteered at the Abraham Lincoln Presidential Library and Museum for 17 years, sharing Lincoln’s story with visitors until his sudden passing last year. Now his family is honoring Navins’s memory with a $100,000 donation in his name.

According to our news partners at WAND TV, the museum said the funds will go toward an exhibit that teaches children about the rights and responsibilities of good citizenship.

Navins spent 22 years in the Navy before retiring as a captain. His sisters said he felt it was important for people to contribute to society as good citizens.
